2.3.0-RC1

Version 2.3.0-RC1
This version has lots of changes, improvements and bug fixes. Please read carefully.

New

1. Fetch now supports notifications via the FetchNotificationManager interface.
   See DefaultFetchNotificationManager class and sample code on usage.
2. Fetch now supports saving downloads to URI paths via StorageResolver.
   See sample code and DefaultStorageResolver class for usage.

• New constructor added for Request object. Request(url, Uri)
• New get method added on Request object. request.getFileUri()
• New get method added on Download interface. download.getFileUri()
• New set method added on FetchConfiguration.Builder class. builder.setStorageResolver(storageResolver)
• New set method added on FetchConfiguration.Builder class. builder.setNotificationManager(fetchNotificationManager)
• New interface added FetchNotificationManager. See java Docs.
• New class added DefaultFetchNotificationManager. See java Docs.
• New interface added StorageResolver. See javaDocs.
• New class added DefaultStorageResolver. See java Docs.

Bug Fixes

• Improvements and bug fixes to Parallel and Sequential file downloader.
• Fixed an issue where the onCompleted method would not be called for downloads with unknown content length.
• Fixed bug where EnqueueAction.DO_NOT_ENQUEUE_IF_EXISTING would throw an exception when it should not.
• Improvements to EnqueueAction.Update_ Accordingly
• Tons of bug fixes and performance improvements.

Breaking Changes

• The Fetch and RxFetch List enqueue method now has a new signature.
  fun enqueue(requests: List, func: Func<List<Pair<Request, Error>>>? = null): Fetch
  See Java Docs for more information. The new signature allows for the case where a request may fail
  to enqueue but other request are still enqueued instead of the whole operation being terminated.
  If the Error is Error.NONE this means that the download was successfully enqueued. Otherwise
  this means that the enqueue for the request failed.
• In order to make Fetch more modular and accommodating to different application environments,
  the following methods were removed from the Downloader interface and are now on the StorageResolver interface.
  If you are overriding these methods, you must extend the StorageResolver interface or DefaultStorageResolver class
  and set an instance on the Fetch Configuration builder you are using to create your Fetch instance.
  Methods Moved:
  fun getRequestOutputResourceWrapper(request: Downloader.ServerRequest): OutputResourceWrapper
  fun getDirectoryForFileDownloaderTypeParallel(request: Downloader.ServerRequest): String
